Abstract Objectives: This study aimed to utilize the large quantity produced from tomatoes in Egypt by processed them in the form of new products ready for direct use in the preparation of various diets with retaining the greatest amount of high nutritional value. Therefore, the present investigation was determined the following: Chemical composition of fresh and different products of tomatoes, Phytochemical for fresh and different products of tomatoes, Phenolic compounds for tomatoes products, The effects of manufacturing and storage period on the composing of tomatoes products, Microbiological examination to tomatoes products and Organoleptic evaluation to tomatoes products.Methods and Results: Methods include chemical composition, bioactive compounds, fractionation of phenolic compounds, antioxidant activity, microbial counts, and sensory evaluation of fresh tomatoes and their products also statically analysis of all samples.Fresh tomatoes had the highest content in all samples of moisture, total carotenoids, lycopene, ascorbic acid and antioxidant activity. Moisture content in canned product no significant change about fresh tomatoes and pH in oven-dried product was the lowest compared to sun-dried and canned product. In addition oven-dried tomatoes had the highest amount of bioactive compounds and antioxidant activity. The canned product had the highest degree of safety since it was found the lowest microbial counts compared to others. Also it had the best results of sensory evaluation thus it had the best acceptability compared with oven and sun-dried products.Conclusion: We neglected very important bio-active tomatoes products and it must be use the high amount producing of tomato in Egypt, since tomato had short shelf life. Throughout, it was processed new products for direct uses in prepared some food meals with preserving most of high nutrition value. Alisa cultivar was used in this study, since it had the best attributes for drying and canning such as firmness, maturity and more pulp, in addition decreased amount of seeds. So, it helped to industry products had good quality. |
